Abstract: TUBE CUTTING APPARATUS            Abstract of the Disclosure Disclosed is an apparatus for cutting elongated tubular material into short individual sections.  The apparatus comprises a plurality of circular knives fixedly mounted in spaced relationship to each other along the axis of a non-rotating shaft.  Rotatable spacing discs having a diameter slightly greater than the diameter of the knives are mounted one on each end of the knife-carrying shaft and are adapted to engage the bare end portions of a rotatable mandrel having a tube to be cut thereon when the knives are moved into cutting engagement with the tube.  The rotatable spacing discs riding on the rotatable tube-carrying mandrel prevent the knives from cutting completely through the tube wall and make possible the retention of very thin, frangible, residual tube wall sections of precise constant thickness at the locations of the cuts.  This allows the tube to be removed from the mandrel in one piece and then broken later, if desired, into individual short sections by hand or machine.

Abstract: Abstract of the Disclosure A system for spray cooling large quantities of heated water has improved spray forming means, comprising spaced groups of associated nozzles connected by piping to pumps, the nozzles having outlets constructed and arranged to discharge the water in a coherent stream which impinges upon the stream ejected by each other associated nozzle of the group, along a common zone beyond the nozzle, with a force which breaks the streams into a spray of drops having a resultant trajectory away from the nozzles into a receiver. The water is preferably aerated before discharge from the nozzles, this being effectively accomplished by means of air inlets to a venturi passage in each nozzle.  Such a system has a higher cooling efficiency, a lower operating cost than the prior known spray coolers, and also avoids the formation of excessive mist.

Abstract: RD-6244 ABSTRACT OF THE DISCLOSURE A variable frequency ac source drives a gas discharge lamp connected as a damping element in an otherwise high Q L-C circuit. Commutation of the ac source voltage is initiated as the instantaneous current drawn from the source equals a predetermined reference current level. Prior to lamp ignition the ac source drives the L-C circuit at resonance causing a voltage buildup which initiates an ignition. After ignition the source limits lamp current to provide a ballasting function.

Abstract: ABSTRACT OF THE DISCLOSURE          A magnetic imaging system wherein a magnetizable recording member comprising a substrate overcoated with a magnetic recording layer of magnetic particles dispersed in a binder is exposed to high energy light pulses of sufficient energy effective to cause or allow the removal of said magnetic recording layer in exposed regions thereof.  Images configured high energy light pulses result in the removal of imagewise configured portions of the magnetic recording layer.  Removal of portions of the magnetic recording layer can occur either before or after magnetization of the magnetizable recording member and upon development with magnetic toner, a complementary magnetic toner image is formed and can be transferred to a receiving medium to form hard copy.  The system is particularly applicable to the formation of a magnetic master which is used to form the same magnetic toner image numerous times.

Abstract: ABSTRACT           A method for dry spraying alpha or beta calcium sulfate hemi-hydrate (CaSO4.1/2H2O) which comprises blowing a stream of dry calcium sulfate hemi-hydrate particles through a hose to a spray nozzle, and prior to discharging the particles from the nozzle onto the surface to be sealed, introducing water into the stream of dry particles and intermixing the calcium sulfate hemi-hydrate particles and the water in the nozzle mixing chamber.  In order to reduce dusting, it may be desirable to add additional water at the nozzle orifice. The amount of water added to the dry calcium sulfate hemi-hydrate particles is an important factor in achieving a satisfactory composition for adhering to and sealing the surface, and generally the method is practiced by using from about 200 to about 100 parts by weight of water per 100 parts by weight of calcium sulfate hemi-hydrate.  The calcium sulfate hemi-hydrate/water admixture sets very rapidly whereby it can be applied in relatively thin coatings and still provide adequate sealing and strength properties.  In some applications, it may be advantageous to incorporate cut glass fibers into the calcium sulfate hemi-hydrate which is preferrably accomplished by introducing the cut glass fibers into the wetted hemi-hydrate particles after they are discharged from the end of the nozzle.  The method of this invention is particularly useful in sealing roof and wall surface in underground mines and may also be used to form structural members in the mines.

Abstract: Abstract of the Disclosure A method of dehydrating carnallite, in which preliminarily enriched carnallite with 39-41 wt.% water is heated up to 205-230°C by fuel combustion products having a temperature of 500-600°C, and a partially dehydrated carnallite with 3-8 wt.% water is obtained.          Said dehydrated carnallite is melted in a reaction zone and the melt is subjected to the action of HCl is a chlorinating agent.        Thereafter the melted carnallite is allowed to settle from solid impurities and, as a result, dehydrated carnallite is obtained with water content less than 0.5 wt.%.  The melting of partially dehydrated carnallite with 3-8 wt.% water is performed with the aid of fuel combustion products containing air and water vapour having a temperature of 1050°C-1150°C. These products are introduced tangently to the surface defining the reaction zone at a rate ensuring the formation of an intensive eddy flow of gases, which occupies the whole volume of the reaction zone.  The partially dehydrated carnal-lite is thrown on the side surface of the reaction zone by the eddy flow due to the action of centrifugal forces, a continuous film of the melt being formed on the side surface of the reaction zone.          Gases containing the products of fuel combustion and the gases liberating upon interaction of the chlorinating agent with the carnallite melt being removed from the reaction zone.  The present invention can be successfully used in titanium industry as well as in magnesium industry in which dehydrated carnallite is one of the types of stock material for electrolytic production of magnesium and chlorine.
